How To Fix TiWorker.exe High CPU Or Disk Usage Problem In Windows

TiWorker.exe or also known as WMI Worker (Windows Module Installer Worker) – is the process of Windows Update service. It’s a required process in Windows and will start when booting up.

Typically, the TiWorker.exe will run in the background of Windows when checking for new updates. It won’t use your resource (CPU, RAM, Disk) until it actually works. When the update process is completed, TiWorker.exe will release your computer’s resources.

However, this process can sometimes also cause high PC’s resource usage, including CPU, RAM, and Disk, in Windows 8, 8.1 and Windows 10. Even Windows Update doesn’t run, TiWorker.exe also hogs the resources and makes it unusable.

In this article, I will show you a few methods that you can use to diagnose and troubleshoot TiWorker.exe high CPU, RAM, or a Disk usage problem, with detailed instructions.

Fix TiWorker.exe High CPU, RAM Or Disk Usage Issue in Windows

1. Manually Check for Windows Update and Install Them

The first step to take to resolve TiWorker.exe (Windows Module Installer Worker) high usage problem is to check for Windows updates manually and install them if any exist.

To check for updates in Windows 8, 8.1, follow the instructions below:

Press Windows + R to launch the Run dialog box.

Type: “wuapp.exe” without the quotes and press Enter.

In the Windows Update window, click on “Check for updates” in the left panel.

Install all available updates if found.

Restart your computer and verify whether the problem persists.

To check for updates in Windows 10, navigate to Settings -> Update & security -> Windows Update. Next, click on the “Check for updates” button, and then install all available updates.

2. Delete SoftwareDistribution Folder

SoftwareDistribution is also known as the Windows Update store folder, where it keeps downloaded updates for Windows.

If one of those files is damaged, then Windows Update can’t work properly. It can’t update features and improvements for Windows which will lead to many other issues, including TiWorker.exe high usage problem.

In this case, you have to force Windows to re-download updates again by deleting SoftwareDistribution folder. To do so, follow the instructions below:

Press Windows + R to launch the Run dialog box.

Type: “services.msc” without the quotes and press Enter.

In the Windows Service window, search for “Windows Update” and stop it.

Go to C:\Windows, find SoftwareDistribution folder and then delete it.

As the recommendation from Microsoft experts, run Windows Update troubleshooter will help to diagnose and troubleshoot problems related to Windows Update. That would be helpful to resolve TiWorker.exe high resources usage in Windows.

To get started, press Windows + X and then P to open Control Panel.

In the Control Panel window, choose “Troubleshooting“.

Look at the left panel, select “View all“.

Click on “Windows Update” from the list and open it.

Click on “Next” button and follow the onscreen instructions to diagnose and fix issues in Windows Update.

3.B – Run Windows System Maintenance Troubleshooter

To use System Maintenance troubleshooter from the Control Panel window, select “Troubleshooting” and then choose “System Maintenance“.

In the next step, click on “Next” button and then follow the onscreen instructions to use System Maintenance troubleshooter.

It will automatically diagnose your Windows system and resolve the problem if there is any available.

Sometimes, corrupted system files can cause this high resource usage problem in Windows. You can use SFC command in Command Prompt to scan and fix corrupted files.

To get started, press Windows + X, then A to open Command Prompt with administrator privilege.

If the User Account Control is enabled, then you have to choose “YES” to open Command Prompt.

In the Command Prompt window, type:

sfc /scannow

and press Enter.

You have to wait until the SFC scan process is completed and then reboot your computer. Check again whether TiWorker.exe is still using a lot of resources (CPU/Disk).

Note: When the SFC tool is scanning your computer, do not use it.

5. Use the DISM Tool to Fix Windows Corruption Errors

DISM Tool, also known as System Update Readiness Tool, is a tool to help you scan your Windows system to find corruption errors and fix them automatically.

This tool is also useful in case the SFC command finds corrupted files, but can’t fix them.

To use the DISM Tool, press Windows + X, then A to open Command Prompt with administrator privilege.

In the Command Prompt window, type:

Dism.exe /Online /Cleanup-Image /Restorehealth

or

Dism /Online /Cleanup-Image /RestoreHealth

Both commands are the same.

Wait for the process to complete and then reboot your computer to verify whether TiWorker.exe high resource usage problem persists.

You can also use Reimage Plus program to scan and repair any Windows system corrupted files. It’s a freeware! Visit here to find out further.

According to some users of Microsoft forum, scanning and repairing corrupted files helped them to resolve “System And Compressed Memory” high CPU usage problem in Windows 10.
